Yes. If the "Corrected" Marketplace statement reflects different information than what you filed on your return, you will need to amend your return to make the appropriate changes.
Since your return was accepted and you have already received your refund, go here and get instructions for amending your return. Amended returns have to be printed and mailed in and take up to 16 weeks to be processed.
One important note: Before you start the process of amending the return in TurboTax, be sure you have printed a copy of your original return or have saved a PDF copy to your computer.
